RS660 on track at Oulton and Cadwell Park. It's first test ride for the baby Aprilia

[@RussTnut]

The sound of this is amazing, I love it 👍🏻😎

[@gogocro1]

Absolutely wonderful sound of the RS660, and that is coming from a VFR 800 owner.

[@philwaldron2127]

More track footage please bike sounds amazing

[@steven-vn9ui]

You looked very smooth out there Dave. Bike is strong, your mods are all working so well toegether. Great video!

[@bobbyblueace]

Sounds awesome in your riders's POV footage!

[@geoffheard5768]

Well done Dave. Love your ENTHUSIASM for riding/racing. Sometimes, ya just have to stop fiddling with it, and ride it til it BADLY misbehaves. Then you know you need to change something. Hope the miss fire is not a serious problem. Looking forward to your first serious hit out. Enjoy!!

Damn Dave, this bike sounds & goes unbelievably grouse!✅ Whether it’s you or the settings, this is an incredible machine 🥇🚀

Been waiting for this one. Nice to see the bike out on track. Also doing low 1:43s around Cadwell on a 95hp 660 tells me I should be able to do below that on my Mille.

[@andrewlucas6214]

Great video. Will be interesting to see comparison times between this and previous bike at same track.

[@daddy5225]

What an awesome sounding engine!

[@ChumiStu]

Sounds amazing, be nice to have a track side fly by 💪

[@nickrider5220]

Thanks Dave, great video 👍🙂

[@flipsideracing]

That little ape sounds great. 👍🏻

[@ChasingTenths]

Great stuff mate , I think the aero on that kit will really help you

[@obsession_engineering]

It's definitely a good fit for my shoulders and head, so far wind protection is spot on

[@kawi704racing]

Bike looks great.

[@paulprescott7913]

Be interesting to see how the RS660 goes around the Isle of Man.

[@Crazeeetwins]

Love it it's brilliant 👌

[@984francis]

40kph is 25mph precisely. At the third beep, it will be 25mph precisely.

[@lonniejoraskie4440]

Awesome vids. Definitely like the track view & rear foot action views for the videos as the dash view just leave a lot to be desired. I do however get the fact your looking at all aspects of the bike while in testing.

[@paulwhite7475]

On board camera position sux

[@MrSportster12]

Good video. The bike sounds great. Just one thing, are you sure the T.T. is going to be dry all week this year?

[@obsession_engineering]

We can only hope!

I rather have used an old 2010 ZX6R than these modern "sports" bikes.

[@obsession_engineering]

Not ideal for a TT supertwin race though 😂

[@teamtempest844]

@@obsession_engineering I wouldn't have tried to enter an inline 4 into a twin race, it's seemingly for youths at that twins pace.

Wow!!
